Hello,
I have a problem with connecting to a http server.
The http server is a cross compiled legacy app which is locally running on the FX30 CAT M.
I could reach the http server via SSH commands like “wget” or “curl”.
I adapted the “httpGet” sample to execute curl commands to reach the http server on the localhost. Unfortunately I always get the error message “curl_easy_perform() failed: Couldn’t connect to server”.
The application is unsandboxed and the http server is listening to the port which I proved with the command “netstat -ln | grep -PORT”.
Does somebody have an idea what the problem could be?
i tried on curl console command, no problem is found:
root@swi-mdm9x28-wp:~# app start wifiWebAp

Via SSH Terminal it’s also possible for me to connect to the server:
The code of the curl command in the application is the following one:
The result is:
no problem is found on my side with WP76 Fw13.3.
You can use my app attached here.
http_get_WP76.zip (3.2 MB)
before running the application, you can start the http server by “app start wifiWebAp”
Thanks, but also your app is not working on the device. I started the app “wifiWebAp” and adapted your app to my target platform: WP77 R9.1.
Same result:
can you try the same FW as mine?
As I’m still using the developer studio the last available fw I can use is R11, but it’s also not working with that one.
I have no idea why it is not working on WP77 FW R9.1 or R12…
As a workaround, I tried on WP77 R9.1, we can use the following instead of 127.0.01 in httpGet.c
static const char * Url = “http://192.168.2.2:8080”;
